Title: Photoelectric switch
Inventor: CHIGA TADASHI
IPC: H01H35/00
Filed: 1993-01-20
Abstract: PURPOSE:To easily execute adjustment of an optical axis in the photoelectric switch. CONSTITUTION:A photodetecting signal is held by a peak value holding means 25 in a microcomputer 23 through an S/H circuit 21. In such a state, by setting the lowest threshold to a comparator 22, the photoelectric switch is turned. When the photodetecting signal exceeding the threshold is obtained during this time, a peak value is held by the peak value holding means 25. When the threshold becomes lower than that of the comparator 22, the threshold is updated to a higher value. In such a way, by allowing the threshold to ascend successively, an optical axis is adjusted. In this way, an optimal optical axis can be adjusted easily by only turning the photoelectric switch.

Filed: 1992-02-13
Abstract: PURPOSE:To provide a cathode-ray tube capable of preventing contamination of a neck end portion, which tube has a good sealing configuration. CONSTITUTION:In an interior graphite coating apparatus for injecting nozzle 22 into a funnel 2 of a cathode ray tube and coating it onto an inner surface of the funnel 2, a coating material recovery means 21 for recovering an excessive conductive coating material coated onto the inner surface of the funnel 2 is vertically movably provided, the coating recovering means 21 being kept in close contact with a neck end portion 9 so as to recover the conductive coating material. With this arrangement, no adhesion of the conductive coating onto the neck end portion occurs to enable funnel coating film formation of any one of a drop-seal system and a butt-seal system. This enables change in product type in speedy response to the movements of the markets, thereby enabling highly efficient production. Further, since the excessive conductive coating material falling from the neck portion of the funnel has no fear that foreign matter enters thereinto, re-use is possible. Thus, the use frequency is increased.

Title: Method of controlling fuel injection of multi-cylinder internal-combustion engine
Inventor: OONISHI AKITO
IPC: F02D41/34
Filed: 1983-02-18
Abstract: PURPOSE:To provide a supply pattern of fuel by controlling a fuel injection amount injected synchronously right after asynchronous injection on the basis of asynchronous injection timing in acceleration. CONSTITUTION:A fuel amount corresponding to the running condition of a multi- cylinder internal-combustion engine is injected in a predetermined cycle synchronized with the rotation of a crankshaft of said engine, while, in an acceleration operation of said engine, asynchronous injection is controlled such that a necessary amount of fuel is injected asynchronously with the rotation of the crankshaft according to the acceleration condition separately from the synchronous injection. When the asynchronous injection is carried out by this acceleration operation and the rotational angle of the crankshaft in the asynchronous injection is within a predetermined range, a fuel injection amount synchronously injected right after the corresponding asynchronous injection is calculated according to the running condition by CPU30 to be decreased or increased, compared with the amount obtained from CPU. Thus the supply pattern of fuel is homogenized without any large variation by the asynchronous injection timing to eliminate dis persion of maneuverability such as acceleration responsive property or the like.

Title: Skew distortion correcting unit
Inventor: WATAYA YOSHIZUMI
IPC: G11B20/02
Filed: 1979-03-09
Abstract: PURPOSE:To correct skew distortion securely by controlling a voltage control oscillator for charge-transfer-element drive by a voltage equivalent to a skew value obtained by detecting the skew distortion. CONSTITUTION:Since output (a) of synchronizing separator circuit 2 is inputted to pulse delay circuit 9, its output signal (b) is formed of pulses lagging an input signal by constant delay time (gamma). Phase difference detection circuit 10 generates a signal for phase comparison by using output signal (b) of pulse delay circuit 9, and samples phase comparison signal voltage (c) by the synchronizing signal. Output signal waveform (d) of phase difference detection circuit 10 obtained in this way differs in value from sampled values before and after skew distortion. On the basis of head switching position information from terminal 12, voltage control oscillator VCO6 is controlled by signal (e) obtained by holding the sampled value of the skew distortion in one-track scanning period voltage holding circuit 11, thereby obtaining a signal with no skew distortion from charge transfer element 7.

Abstract: PURPOSE:To obtain a Ti sheet showing excellent scratch resistance at the time of secondary working, such as tube making, by subjecting a Ti sheet cold-rolled by the use of rolling oil with inferior lubricity to annealing under the condition where the amount of oil adhering to the surface, etc., are specified. CONSTITUTION:The cold rolling of a Ti stock is carried out by using rolling oil of <=170mg/KOH/g saponification value, by which a Ti-sheet 1 in which scalelike ruggedness 2 is formed in great numbers on the Ti-sheet 1 surface and also fine and homogeneous Ti powder 3 is formed in large quantities on the Ti-sheet 1 surface and allowed to adhere in a state mixed with the rolling oil to the Ti-sheet 1 surface is formed. This sheet metal is annealed in a nonoxidizing atmosphere under the condition where the amount of oil adhering to the surface is regulated to >=10mg/m<2>. By the above procedure, the above ruggedness 2 enlarges the reaction interface between C component in the rolling oil and the Ti-sheet 1 surface and the above powder 3 is allowed to react with C formed by the thermal decomposition of the rolling oil at the time of annealing, by which a hard surface hardened layer 4 composed principally of TiC is formed on the Ti-sheet 1 surface. Accordingly, the Ti sheet excellent in scratch resistance at the time secondary working can be obtained.

Abstract: PURPOSE: To obtain H 2  gas and a mixed gas of CO, CO 2 , and CH 4  separately, relatively inexpensively, by reducing an oxide of a metal of the II or III group with a carbonaceous raw material, bringing the reducing substance into contact  with H 2 O, and consuming repeatedly water and the carbonaceous raw material.  
     CONSTITUTION: An oxide shown by the formula MXOY of a metal of the II or III group is blended with carbon or a carbonaceous raw material and heated to carry out a reaction shown by the formulaI, and the oxide is reduced to a metal element and/or lower oxide shown by the formula MXOY -n . The reduced substance from the former stage is brought into contact with water and/or steam to evolve H 2  by the reaction shown by the formula II and simultaneously to oxidize the reduced substance. Since in the operation the MXOY is specified as above-mentioned, water decomposition at low temperature of about 300°C can be attained. The reduction temperature, depending upon the kinds of the metal M and carbonaceous the raw material, is preferably ≥ about 400°C. If the temperature is too high, a high-quality material is required for a reaction tube, so  it is not advantageous. The practical temperature of water decomposition is  about 200W500°C.
